A 65 ?kg human is exposed to 32.3 rad of radiation. a)How much energy was absorbed by the person's body? Express your answer using two significant figures. b) Compare this energy to the amount of energy absorbed by a person's body if he or she jumped from a chair to the floor (assume that the chair is 0.50 m from the ground and that all of the energy from the fall is absorbed by the person). Express your answer using...

How much energy is required to accelerate a spaceship with a rest mass of 105 metric tons to a speed of 0.522 c? Submit Answer Tries 0/20 Every day our Earth receives 1.55x1022 ) energy from the Sun. If we were able to use 0.85 percent of this energy to accelerate spaceships, then how many missions would be possible in one year? 10
Problem 30.53-MC Review I Constants A 95 kg patient swallows a 31 Ci beta emitter whose half-life is 5.0 days and whose RBE is 1.6. The beta rticles are emitted with an average energy of 0.35 MeV, 90% of which is absorbed by the body. You are a health care worker needing to find the patient's dose equivalent after one week. These series of steps will help you find that dose equivalent. In all questions, assume the radioactive nuclei are...
Please answer all parts and show all work 11. (50 pts) A 4.0 kg mass is connected by a massless string to the rim of a pulley. You can assume that the pulley is a cylindrical shell has a radius of 0.50 m and a mass of 11.6 kg, as shown in the figure and that the string does not slip on the pulley. The mass is released from rest at a height of 2m above the ground. a. (10...
